Cambium's 5 GHz PMP 450i subscriber provides high performance wireless data connectivity by connecting back to a PMP 450i Access Point. The unit's integrated antenna encapsulates all RF connections within its weatherproof radome, minimising potential points of failure.

Coupling its 40 MHz channel width with a peak modulation scheme of 256QAM the PMP 450i can provide beyond 300 Mb/s L1 throughput (theoretically as high as 450 Mb/s). The 450i system touts a maximum range of 64 kilometers (subject to regulatory conditions).

PMP 450i 5 GHz is one of few industrial grade multipoint solutions. The system is the choice of major mining and telecommunications companies where performance cannot be compromised. The unit is IP67 rated for harsh operating environment and claims a mean-time-between-failure of over 40 years.

The unit's integrated 23 dBi antenna provides high speed connectivity out to about 10 to 15 kilometres, although this is of course dependent on the required data rate and tolerated latency / jitter performance metrics.

PMP 450i is one of our favourite units for the simple fact that it does exactly what it states. There's no marketing spin, the system is installed and provides continuous high speed wireless connectivity for decades. The AP is rock solid and operates in just about any environmental condition.

A unique feature is its FPGA design, allowing future firmware releases to upgrade performance.
